Cytokines and embryo implantation
Journal of Reproductive Immunology, 1998The implantation process is currently considered the most relevant limiting factor for successful pregnancy. It is evident that molecular interactions at the embryo-maternal interface at the time of implantation are crucial in order to understand the mechanisms of embryonic implantation.

Implantation is an essential step in the development of a pregnancy, but often fails in humans. In assisted reproductive technologies, implantation failure continues to impair treatment outcomes, with distressing results for patients and physicians.Morphokinetics, comprehensive chromosome screening, and the analysis of embryo-derived products ...

Determinants of Embryo Implantation: Roles of the Endometrium and Embryo in Implantation Success
Reproductive Sciences, 2023Both uterine endometrium and embryo contribute to implantation success. However, their relative role in the implantation success is still a matter for debate, as are the roles of endometrial receptivity analysis (ERA), endometrial scratch (ES), endometrial microbiome, and intrauterine or intravenous measures that are currently advocated to improve the ...

Lipid signaling in embryo implantation
Prostaglandins & Other Lipid Mediators, 2005A reciprocal interaction between the implantation-competent blastocyst and the receptive uterus is required for successful implantation. Although various molecular pathways are known to participate in this cross-talk, a comprehensive understanding of the implantation process is still missing.

Embryo-uterine interaction in implantation
Life Sciences, 1980Abstract Pregnant donor (day 3) and non-pregnant recipient rats were hypophysectomized and injected daily for 6 days with 2 mg of progesterone. A single dose of 20 ng of estradiol-17β in saline was administered via a tail vein to either the donor, the recipient, or to both animals; blastocysts were transferred 60 to 90 minutes after the latter ...

Uterine embryo implantation: the endometrium, seminal plasma
2023Omkring 17,5% af verdens voksne befolkning oplever fertilitetsproblemer. Selvom der er en rivende udvikling inden for feltet, er manglende implantation i livmoderen ikke sjældent en begrænsende faktor. Forudsætninger for succesfuld implantation af et normalt udviklet befrugtet æg (embryon) og en modtagelig livmoderslimhinde (endometrium), som er under ...

Antibodies, implantation and embryo survival
Reproduction, Fertility and Development, 1992The diverse strategies adopted among species for the maintenance of luteal function converge to meet the indispensable requirement for this hormone particularly at the time of onset of implantation. What has emerged from immunization studies is the difference that exists between various species in the effects of progesterone depletion.

Uterine contractility and embryo implantation
Current Opinion in Obstetrics & Gynecology, 2005The aim of this article is to assess the importance of uterine contractility in the implantation of human embryos.Recent findings show that the receptive phase of the endometrium seems to occur in close association with the appearance of pinopodes and endometrial integrins that may be activated by the IL-1 system.
